Marko Sample - scoped-variables

In this sample app we create a custom tag with the following usage:

<date-now var="now">
    The current time is $now.time.
    The current date is $now.dayOfWeek, $now.month $now.dayOfMonth, $now.year
</date-now>

The <date-now> custom tag introduces a scoped variable by declaring the vars property in the taglib/date-now/marko-tag.json file as shown below:

{
    "renderer": "./renderer",
    "@var": "identifier",
    "vars": [
        {
            "name-from-attribute": "var"
        }
    ]
}

The renderer for the <date-now> tag provides the value of the variable when invoking the renderBody(out, var1, var2) function as shown below:

var now = {
    time: ...,
    dayOfWeek: ...,
    ...
};

renderBody(out, now);
